Description
When kernel finished downloading all bundles and creating the final merged-rt.jar, just keep kicking off "java -version", and you will run into problem.   multiple java process will be spawned, and final merged-rt.jar won't be created.
Comments
EVALUATION Fixed mainly by ensuring that only the background download thread performs merges, along with a little bit of mutex shuffling.

EVALUATION Looks like the problem is it's possible to spawn a new background download process during the creation of merged-rt.jar. Right now BackgroundDownloader will quit immediately when "background" mutex cannot be obtained; maybe we should also check the "completion" mutex too ?
